Phytophthora Root and Collar Rot in Rehabilitated Bauxite Mines and the Adjacent Eucalyptus Marginata (jarrah) Forest of Western Australia
Western Australia is unique in its botanical diversity. There are over 7000 species of native vascular plants of which over 3000 are endemic (Keighery 1992). Phytophthora cinnamomi has a major impact on this diverse flora and directly effects over 2000 species from a diverse range of plant families (Wills 1993). Its indirect effects in terms of botanical impact through the loss of vertebrate an...
متن کاملThe effects of eucalypt plantations on plant litter decomposition and macroinvertebrate communities in Iberian streams
Eucalypt plantations cover over 1.5 million ha in the Iberian Peninsula. The effects of the replacement of native deciduous forests by exotic plantations on stream communities and litter decomposition, a key ecosystem process in forest streams, are poorly understood. We compared microbially driven and total (microbes + invertebrates) decomposition of alder and oak leaf litter (high and low qual...

15 صفحه اولLitter quantity and decomposition
The global terrestrial heterotrophic respiration is estimated at about 60 Gt C yr-1 (Schlesinger, 1991). Plant litter produced during senescence processes and plant residues left on site after harvest operations are the primary substrate for heterotrophic respiration in plant-soil ecosystems. They constitute both of aboveground and belowground plant parts. Substrate quality, together with the p...
متن کاملNothofagus Litterfall and Litter Decomposition
South Chilean forest ecosystems represent one of the largest areas of old-growth temperate rainforests remaining in the Southern hemisphere and have a high ecological value, but suffer from deforestation, invasion by exotic species, fragmentation, and increasing atmospheric nitrogen (N) deposition. To support sustainable forest management, more knowledge is required on nutrient cycling of these...
